  Fabrication of deoxycholic acid tethered α-cyanostilbenes as smart low molecular weight gelators and AIEE probes for bio-imaging

  摘要：

  Four novel deoxycholic acid tethered alpha-cyanostilbenes were designed, synthesized and characterized using detailed spectroscopic analysis. The synthesized deoxycholic acid tethered alpha-cyanostilbene derivatives formed stable gels with a variety of solvents, such as xylene, toluene, mesitylene, decane, dodecane etc. The stable gels showed lamellar sheet type structures stacked over each other, consisting of entangled fibres as evident from SEM, TEM and Fluorescence Microscopy images; The synthesized compounds exhibited AIEE behaviour in H2O/THF mixture, with the maximum emission observed in 70% H2O/THF fraction along with a bathochromic shift. A solvent thickening experiment was perform to establish the mechanism of AIEE and the AIEE property was explored for bacterial bio-imaging. The synthesized derivatized steroids proved their potential as multifunctional organic materials.

  Discrete polymers offer an excellent platform for comprehending the interplay between precise chain structures, distinctive self‐assembly behavior, and functional applications, whereas the development of discrete polymers with self‐immolative properties remains scarce. Here, we modularly synthesize a library of discrete self‐immolative oligourethanes containing N‐naphthylcarbamate or N‐(3‐fluorophenyl)carbamate repeating units via iterative stepwise growth. These oligourethanes undergo not only cascade 1,6‐elimination depolymerizations via photo‐mediated removal of o‐nitrobenzyl carbamate triggers but also selective cleavage of benzyl‐O linkages under MS/MS conditions even without UV light irradiation. In aqueous media, these discrete oligourethanes self‐assemble into different morphologies such as flat nanosheets, nanofibers, and nanoribbons, depending on the chain lengths and backbone compositions, and further morphological transitions are observed upon thermal annealing.

  摘要 离散聚合物为理解精确的链结构、独特的自组装行为和功能应用之间的相互作用提供了一个极好的平台，而具有自惰性的离散聚合物的开发仍然很少。在这里，我们通过迭代逐步生长的方法，模块化合成了含有 N-萘基氨基甲酸酯或 N-（3-氟苯基）氨基甲酸酯重复单元的离散自褪色低聚氨基甲酸酯库。这些低聚氨基甲酸酯不仅会通过光介导的邻硝基氨基甲酸苄酯触发器的去除而发生级联 1,6- 消除解聚，而且在 MS/MS 条件下，即使没有紫外光照射，也会发生苄基-O 链接的选择性裂解。在水介质中，这些离散的低聚氨基甲酸乙酯会根据链长和骨架成分的不同自组装成不同的形态，如扁平纳米片、纳米纤维和纳米带。
